CASH-REGISTER.

Patented Feb. 4. 1913.

Application filed October 20, 1906. Serial No. 339,793.

To all whom it may concern:

' Be it known that 1, WILLIAM M. -Mo- 'CARTHY, a citizen of the UnitedStates, re-

siding at Dayton, in the county of Montgomery and State of Ohio, haveinvented certainnew and, useful Improvements in tion.

This invention relates to cash registers out counter device.

{A further object is to provide a throwout counter mechanism in whichthe register operating devices are locked from operation when thecounteris to be thrown out,

in contradistinction to that type of ma chine in which the operatingdevices are prevented from engaging the counter.

Another object is to provide means for With these and incidental objectsin view,

tures of construction and combination of parts, the essential elementsof which are set forth in appended claims and a preferred form ofembodiment of which is hereinafter specifically described with referenceto the drawings which accompany and form part of this specification.

Of said drawings: Figure 1 is an end elevation of the right hand side ofthe machine showing the printing mechanism. Fig. 2 is a verticaltransverse section through the machine. Fig. 3 is a rear elevation ofthe indicators and their connecting mechanism. Fig. 4 is a detailsection on line 44 of Fig. 3, looking in the direction of the arrow,crossing said line. Fig. 4* is a detail front elevation of theregistering gears and their locking arms. Fig. 4" is a detail plan viewof pawls 95, the latching arm 90 and latch pin 89. Fig. 5 is a detailsection through the machine, showing in particular the release key; andFig. 6 is a detail view of the power spring and clutch for same. 7

This invention is shown as applied to that class of machine known as theUnion cash register, but it can be said that the particular arrangementand design of the parts shown is not essential to the correct working ofthe mechanism, it being understood that it is intended to show in thesedrawings and specifications a principle which may be applied to any oneof several different types of machines now well known in the art. l

A' brief description of the general operation of the mach-inc will begiven, which, with reference to British Letters Patent No. 22535 of 1904to Fuller, will enable any one well versed in the art to fullysundcrstand my invention as being well adapted to fulfil the objects asstated'above.

Referring to-Fig. 5, it will be seen that when any one of the keys 10 isdepressed it is latched in its operated position by one of a series-ofhook fingers, formed upona detent plate 12, engaging a laterallyextending pin 12 on said key. The pin of'each key extends through to theopposite side (Fig. 2) and contacts a spring drawn curved arm 13, whichis loosely mounted upon a transverse shaft 11, thereby withdrawing arearwardly extending portion 13 of said arm out of the path-of. a pin 14mounted upon a rack segment 15. This segment is operated by a springdrawn gear wheel 16, and is limited in its movement by a pin 17 mountedthereon which contacts with the lower end of a depressed key. Thereforeit will be plainly seenthat (providing the gear 16 is free to revolve)when a key is depressed and latched in itsdepressed. position by thedetent 1.2, the segment 15 will be released and rocked in the directionof the arrow :1 distance depending upon the key depressed. The gears 16,of which there is one for each denomination, are geared through pinions18 to the front indicators 19, and through pinions 20 and shafts 21 tothe registering and back, indi cating operating mechanisms, as will behereinafter more fully described.

All of the above mentioned parts are nor mally locked from operation andare only released by the operation of a. key 22 (Fig. 5), which rocksshaft 11 by means of a forwardly projecting arm 22 thereby withdrawingpawls 23, fast to saiilshaft, from out of engagement with the gears 1'6.-5 A rearwardly extending portion35of the arm 22, which engages ashoulder 25 formed upon a segment 25 and latches the latter frommovement, is also withdrawn thus freeing said segment: The keys 10 arelocked from operation, upon depressing the release key, by arms 36secured to the shaft. 11 engaging shoulders 36 formed upon detent plates12.

The segment is loosely mounted upon the main shaft 13, and meshes with apinion 26 mounted on a shaft 27 and having an extended hub 28 formingone part of a toothed clutch (Fig. 6). To the hub 28 is fastened one endof a spring 29, the other end being fastened to the frame work of themachine. A collar 30 forming the other part of. the clutch is connectedto the shaft 27 by a pin and slot connection and is spring pressedtoward the hub 28. Upon depressing the-release key 22 the pawls 23 andthe arm 35 will be withdrawn from the gears 16 and the segment 25respectively, allowing the spring 29 to rotate the shaft 27 throughmeans'of the above described clutch. Extending from one side of wesegment 25 is a flange 30*, against which atiits at 39 a spring drawnarm 38 pivoted on a shaft 37. The lower end of the arm 38 is jIOVldEdwith a hook 40 which engages a projection41 of the clutch collar 30after the latter has made a complete revolution, just previous to whichthe flange 30 has been carried away from the part 39 of the arm 38,allowing the latter to be drawn forward by its spring to arrest theshaft 27. Adjacent to the segment 25 is another segment 31 rigidlysecured to the shaft 13"", upon the outer end of which is fastened anoperating handle 32. The upper edge of the segment 31 is arranged tocontact with the flange 30, and. return the segment 25 and pinion 26 tonormal position and thereby rewind the sprin 29, upon the oscillation ofthe handle 32. when the release key 22 is depressed and the handle 32moved rearwardly, a

flange 33 formed on the segment 31 enters a recess 34 in the release keyand prevents the withdrawal of the latter until the flange 33 passes outof the recess, oywhich time the shoulder 25 of the segment 25 presentsitself to the arm 35, which is drawn into engagementtherewith and therelease key thrust forwardly by a spring atO I The flange 33 alsoprevents the operation of the release key, if the handle is operatedfirst, by passing under the end of said hey.

Referring now to Figs. 1 and 3, it will be seen that the shafts 21extend to the outside of the machine and have pinions 50 secured theretomeshing with rack segments 51 formed upon printing wheels 51. As theshafts 21 receive different degrees of movevment, depending upon thekeys depressed (as before explaf aed), it will be clear that theprinting whens will rezi'eive like mcwc ment to bring the correctnumerals into printing alinement. This printing mechanism as hereinshown is identical with that shown and described in the aforementionedpatent to Fuller, to which atent reference may be had for a moredetailed description. As seen in F ig. 3, another set of indicators isprovided to be read from the back of the machine. These indicators havefastened to them pinions 57 which mesh with gear wheels 56, which inturn mesh with pinions 58 secured to the shafts 21. To the latter arepinned pinions 20, which are driven by gear wheels 16 as hereinbeforedescribed. Each amount indicator operat ing shaft 21 is provided with ahub 63, which rotates with said shaft but has a slight lateral movementindependent of it, which is provided for by a slot and pin connection65. A tooth 64 of the hub 63 engages a notch formed in the hub of apinion 61 loosely mounted on the shaft 21. This pinion meshes with aspring drawn register operating gear wheel 60, mounted on the shaft 37adjacent to the gear wheel 56 (Fig. 4). The gear 60 meshes with acounter actuating gear 66, upon which is mounted a spring pressed pawl67 engaging a ratchet 68 attached to a counter wheel 69. Thus it will beseen that when the gear 60 rotates notches in the hubs of the pinions 61and the shafts 21 will rotate independently of the pinions 61. Thelocking of the gears 60 to prevent the counter from being actuated, isaccomplished by the pressing in of any one of three special keys 70,which represent different es of transactions such .as Charge, Paid outor Reed/on acct, in the following manner. Mounted rigidly upon a shaft71 Fig. 2) a downwardly extenting arm '72. which is limited in itsmovement by an elongated. slot 73 embracing the. Sllflfi i1, and isdrawn to its normal position by spring 7%. Upon the shaft 71 are mounteddownwardly extending locking arms 75 (Figs. at and at), one for eachregdepressed keys.

and the other is made fast to the, shaft 13. As the shaft is oscillatedby the handle 32, the rod 81 will contact with all of the displaced arms82 of the segments 15 and restore them with the indicators and theregistering gears 30 to their home position, the latter by the teeth 64of the hubs (i3 engaging the notches formed in the hubs of the pinions(31, if the sale has been registered; if the sale has not beenregistered, the gears 60 and the pinions 61 having been locked in theirnormal position, the hubs 63 will be returned independently. Byreturning the parts beyond their normal position, the rod 81 contactswith the under sides of the detent plates 12 and raises them to releasethe The segments are latched in this position by the pawls 23 engagingthe gears 16, while the detents return to their normal position upon therearward movement of the rod 81.

As is well known cash registers as now constructed are provided withmechanisms fo performing ditlcrent functions. such as indicating,registering, and rewarding of amounts previously determined. \Vhile inthe s 'iccilic embodiment of the invention herein disclosml there havebeen shown devices f r preventing a movement of the actuators of theregistering mechanism when it is desired to perform the functions ofindicating and recording without registerin yet it to be understood thatthis invention is not limited to this specific embodiment, but that theactuators for the mechanisms for pcrfori'ning other functions of themachi. may equally as oil. be prevented from nim'ing.

To arronpl he other object of this inveini n'i Ire wallow. mechanism isemployed: Loo *l pivote on the shaft 13' (Fig. t; is a 1 %il-t121lll armH5 provided at its lower cud with an enlarged slot 86, Whirl 1n:brarctand with an aiililrmina he en-- gagzco The ,v rile l with whi hncrniatly engaged by a arm pii at at 31, and having rilly (Xit a.carrying a ,ukWl H l m ll; 192% mount- Hindi the rvlc; in ntacis, whensaid tev is operat eii loosely upon the, shatt 1 besiil a, in R5 arepawls a! 60, which it?) their rethe ends of ivc gears by which areconnected to the pawls and to the. r d 9.

The antifriction roller 87 now being inits downcammed into engagement with the gears 60 until the latter havemoved to the position determined by the depressed keys.

The operation of the mechanism will, it is thought, be obvious from thedescription. It will be seen that a mechanism has been provided whichpositively locks the operating mechanism for the counter when a specialtransaction key is depressed and there by prevents the operation of thecounter. The locking devices shown in Fig, 4 while permitting the returnof the registering gears under any condition, prevent the forwardmovement of said gears except at the proper time thereby overcoming thedefect of pumping the counter by moving the type wheels back and forthby hand.

While the form of mechanism here shown and described is admirablyadapted to fultil the objects primarily stated, it is to be understoodthat it is not intended to con fine the invention to the one form ofembodimcnt herein disclosed, for it is susceptible of embodiment invarious forms all coming within the scope of the claims which follow.
